Hey guys I need some help with my c++ snek program

Question

The getch isn't working the way I want it to.

namespace sense {
    using namespace sense;
    
    void change_direction() {
        if ((c == 'd') && (direction != "left")) {direction = "right";}
        if ((c == 'a') && (direction != "right")) {direction = "left";}
        if ((c == 'w') && (direction != "down")) {direction = "up";}
        if ((c == 's') && (direction != "up")) {direction = "down";}
    }
    
    void sense_keypress() {
        if ((c == 'a') || ((c == 'd') || ((c == 's') || ((c == 'w')) {d = c;}
        initscr();
        timeout(100);
        c = getch();
        endwin();
        
        if ((c != 'd') && (c != 'a') && (c != 'w') && (c != 's')) {c = d;}
        cout << c;
        if ((c == 'd') && (direction != "left")) {direction = "right";}
        if ((c == 'a') && (direction != "right")) {direction = "left";}
        if ((c == 'w') && (direction != "down")) {direction = "up";}
        if ((c == 's') && (direction != "up")) {direction = "down";}
        
        cout << direction;
    }
    
    
}

int doit = (100000 - (level_num^10));
